A support plate 17 is fixedly connected to the top of component 1. A second groove is provided on the inner side of the support plate 17. A second motor 18 is connected to the top of the support plate 17. A stud 19 is fixedly connected to the output end of the second motor 18. The stud 19 is rotatably connected to the second groove. A second moving block 110 is threadedly connected to the surface of the stud 19. A connecting block 111 is fixedly connected to the side of the second moving block 110. A limit ring 112 is slidably connected to the inner side of the connecting block 111. An adjusting roller 113 is rotatably connected to the inner side of the limit ring 112. During operation, the cable is passed through the bottom of the two transmission rollers 16. The cable in the middle section is passed through the top of the adjusting roller 113. When the cable moves, it drives the transmission roller 16 and the adjusting roller 113 to rotate. When the cable tension needs to be adjusted, the first motor 12 drives the positive and negative thread screw 13 to rotate. The positive and negative thread screw 13 drives the first moving block 14 to move on the top of the base 1. The first moving block 14 drives the moving seat 15 to move. The moving seat 15 drives the transmission roller 16 to move. To adjust the distance between the two transmission rollers 16, the second motor 18 drives the stud 19 to rotate. The stud 19 drives the second moving block 110 to move. The second moving block 110 drives the connecting block 111 to move, which in turn drives the limiting ring 112 to move, which in turn drives the adjusting roller 113 to move, thus adjusting the height of the adjusting roller 113. By adjusting the positions of the two transmission rollers 16 and the height of the adjusting roller 113, the tension of the cable can be adjusted. This step, by moving the two transmission rollers 16 left and right and adjusting the height of the adjusting roller 113, allows for corresponding adjustment of the cable tension, thereby achieving cable tension adjustment and increasing the applicable range of cable tension adjustment.
